Load Balance Policy
Load Balance Policy is a method of binding specific traffic (such as https traffic) to a particular WAN for the duration
of a session. We will take some examples to explain how to setup the Load Balance Policy for the application that requires traffic to be sent and received from the same IP source.
Case1.
Some applications (HTTPS, FTP, VoIP, Terminal Services, Mail,
etc) are sensitive to public IP address. They will monitor
if your IP changes and log you out if your IP is changed.
For example you may meet the problem that logging into certain
HTTPS sites (e.g. online banking) keep booting you out. Assuming
you want all the HTTPS traffic to be sent from WAN1.
1. Go to WAN >> Load Balance Policy.
2. Click the Index number 1.
3. Enable this policy. Select TCP 443. Select WAN1. Source IP address and destination IP addresses are leaved blank which mean any IP address. Then press OK.
Case2.
Assuming there is a server on the Internet with IP address 202.211.200.130. It acts as Web server, SMTP server and FTP
server. You want all the traffic between this server and internal host to be passed through WAN2 due to its higher speed.
1. Go to WAN >> Load Balance Policy.
2. Click the Index number 1.
3. Enable this policy. Select Protocol any. Select WAN2. Source IP address is leaved blank which mean any IP address. Input the server?s IP address as the destination IP address. Then press OK.
Case3.
Assuming there are two departments in your company. You want the Sales department to use WAN1 and the R&D department to use WAN2.
1. Go to WAN >> Load Balance Policy.
2. Click the Index number 1.
3. Enable this policy. Select Protocol any. Select WAN1. Destination IP address is leaved blank which means any IP address. Input the IP address range for Sales dept. as the source IP address. Then press OK.
4 Click the Index number 2.
5. Enable this policy. Select Protocol any. Select WAN2. Destination IP address is leaved blank which means any IP address. Input the IP address range for the R&D dept. as the source IP address. Then press OK.
